Air enters a 16-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and it leaves the pipe at 180 kPa and 38°C. The gas constant of air is 0.287 kPa·m3/kg·K. Whats the volumetric flow rate of the inlet/outlet, mass flow rate and velocity & volume flow rate at the exit?
Q4) Water (y 9810 N/m3) flows steadily with negligible viscous effects through a pipe as shown below, pressure and velocity at point (1) are 110 kPa and 1m/s respectively. Find the pressure at point (2) in kPa if velocity at that point is 5 m/s. 2 m Answer (round to 1 decimal place):
Water is flowing through a horizontal pipe with diameter, D1, at
a velocity, V1, and under a pressure, P1. It enters a 900 reducing
bend (Shown in grey in Fig 2) that connects to a vertical pipe of
diameter, D2. The inlet of the bend is 50 cm above the exit of the
bend (as shown in Fig 2). Axes for positive directions of x and z
coordinates are provided. Figure 2 Side view of reducing bend from
horizontal to...

If someone puts a nozzle on the end of the pipe, reducing the diameter to 0.35m, at what speed will the water exit the pipe?. 10. A pipe with a radius of 50 cm has water flowing at 5 m/s. If water goes into a new pipe with radius 33 cm, how much will the pressure decrease? 11. A large dam has a hole that is...
Water at 20 C is steadily flowing through a diverging pipe section that is inclined by an angle of 30° with respect to the horizontal (See the figure) The total testing section length is 20 m long with an initial pipe diameter of 10 mm (Section 1) and final diameter of 20 mm (Section 2). The small diameter section shows a gage pressure of 100 kPa and average flow velocity 10 m/s. Other values will be obtained by reaching complete...

1. (15 points) Water (p-1g/cm) is flowing in pipes shown in Figure below. Use Bernoull's equation to calculate velocity of water at point B. - Fluid velocity in the large diameter pipe is 1m/s. - Pressure at point 2 is measured with U-tube mercury manometer (Pmercury-13,600kg/m) - h1-0.3m, h2-6cm - assume that the acceleration gravity g-10m/s 2 Manometer shows 0.7kPa pressure Ji h1

Water at 10 °C (p = 999.7kg/m3 and μ = 1.307×10-3kg/ms) is flowing steadily in a 0.12-cm-diameter, 15-m-long pipe at an average velocity of 0.9 m/s. Determine (a) the Reynolds number and decide weather the flow is laminar or turbulent (b) the head loss, (c) the pressure drop, and (d) the pumping power requirement to overcome this pressure drop.
